Output a list of git committers
By using the git log command formatted and piped to sort -u (unique) you can pretty easily get a listing of who has ever contributed to a project which is under git source control.
git log --pretty=format:"%an" | sort -u
Using this you’ll get an output that resembles something like this.
As you can see, it sorts by the full name string which may not be ideal but I think that it does the job well enough for now.Google+
